Weco Check Valves

VigorPetro's Weco Check Valves are available in both clapper style and dart style, which are placed in the treating line to allow flow to the well but isolate any back flow to go upstream of the valve. This provides protection for equipment at various locations in the flow line by helping to prevent fluid from traveling backup into the manifold area or into the pumps. Two flow directional configurations are offered, including wing-ahead (standard flow) or thread-ahead (reverse flow) models.
VigorPetro recommends that clapper check valves be used in applications in which fluid being pumped contains solid materials, such as proppant. Dart check valves are recommended only for use in non-abrasive media applications, such as nitrogen pumping.

Clapper/Flaper Style Check Valve

VigorPetro clapper / Flaper check valves are manufactured in 1", 2", 3", and 4" sizes for operating pressures in 2000psi, 3000psi, 5000psi, 10000psi, 15000psi and 20000psi. The Claper Style Check valve have two style, Straight Line Style Claper Check Valve and Top Cover Style Claper Check Valve, both styles with hammer union end connections are available in standard or reverse flow, and should be installed with the flow direction arrow machined on the body aligned with the flow direction of the line. The clapper check valves, unlike the dart style, are designed for fluids that are heavily laden with materials such as
proppants, solids, and ball sealers.
The Clapper check valve utilizes unique design features resulting in improved reliability and performance compared to other check valves currently available to the market.

Dart Style Check Valve

dart checK VALVE_VIGORPETRO.COM.png


VigorPetro dart style check valve permits fluid to flow towards the well, while impeding back flow from traveling upstream of the check valve. The valve acts as an independent pressure actuated response system, working immediately following a pressure loss and requiring no operator to be present for initiation.
The dart style valve is constructed of a two-piece body that houses an inline spring loaded dart. When fluid enters from the inlet side, it will overcome the low spring force on the dart. The dart will travel away from the inlet and allow the fluid to flow around towards the outlet. When fluid flow stops, the light spring force closes the dart against its seat, helping to prevent fluid from flowing back through the flow line.
Dart valves are intended for use in services where the fluid media does not contain abrasive materials. For those applications, the clapper check valve will provide enhanced performance and extended life.
